I am Dr. Nigel Irwin from
the University of Ulster School of Pharmacy and Pharmaceutical Sciences.
This presentation is on peptide YY or PYY for short,
and its role in obesity and diabetes.
Essentially the talk will cover,
the idea that PYY can be used as a therapeutic for
both obesity and quite recently it can also be used for diabetes.
This is just some background into the area that I'm going to
discuss today: obesity and diabetes.
They're often grouped under
the same heading diabesity, because they're both very much linked diseases.
Indeed diabesity is considered the new epidemic of the 21st century,
and numbers are increasing at an alarming rate.
It is for that reason that we need to develop drugs to
both manage glucose control in diabetes,
but also with body weight issues in obesity.
So this is just some background into the number
of people presenting with obesity worldwide.
This data is from 2014,
and unfortunately numbers will have increased in the past two or three years.
However there is some alarming things to note on this figure.
You can see all the areas shaded in red, have an obesity rate greater than 25 percent.
So one in every four-person presents with obesity; with
a BMI greater than 30 kilograms per meter squared,
and these numbers, as I said are increasing at a very steady rate.
